You need to specify the exact signature of your didEndSheet_etc method:
returnCode is an int argument and PyObjC can't guess that. After your
method definition, add:

    didEndSheet_returnCode_contextInfo_ =
objc.selector(didEndSheet_returnCode_contextInfo_, signature="v@:@ii")

(I'm not sure I got this right as I don't know where that signature
syntax is defined and I have no time to actually run the code.)
